drawings, forming part of this specification.

rIlhe present invention has for its object to provide an improved devicefor tightening a hose band about the end of a hose for the purpose ofsecurely holding the hose in engagement with a coupling inserted in theend thereof.

The invention consists in the features of novelty hereinafter described,illustrated in the accompanying drawing and more particularly pointedout in the claims at the end of this specification. j'

Figure l is a view in elevation of a hose band tightener elnbodying myinvention, the hose band, a portion of the hose and a coupling beingindicated in dotted lines. Fig. 2 is a view in vertical section on line2-2 of Fig. l. Fig. 3 is a plan view showing one form of hose band foruse in connection with which my improved tightener is especially welladapted.

A designates one end of ay section of rubber hose into which is insertedthe shank of a coupling B, and C denotes the hose band whereby the hoseA will be securely retained upon the coupling B. The band C for use inconnection with which my improved band tightener is more especiallyadapted, is indicated by do-tted lines in the several views of thedrawings. As shown, this band C (which, however, forms no part of mypresent invention), has a hole c at one end and a tongue Z formedintegral therewith and projecting from a point adjacent the opposite endof the band.

When my improved tightener is to be used in applying a hose band of thekind Aillustrated, the band C will be placed about that part of the bodyA of the hose that extends over the shank or reduced portion of thecoupling B with the ends of the band overlapping and with the tongue dextending upwardly through the hole c as indicated in dotted lines inFigs. l and 2.

My improved tightener comprises a body portion E that is chambered toreceive a sliding head G that is carried by the screw H. From the head Gprojects a pin g adapted to engage the end of the band to be tightened.A nut K having arms or wingsu r engages the screw H. The nut K bearsagainst the top of the body E and by turning the nut lthe screw H can bemoved upward sol as to cause the head G andl 4its pin g to draw upwardthe end of the hose band and thus tighten itaround the hose, As shown,the lower portion of the body E vhas rounded or ovoid surfaces c adaptedto rest uponand fit the overlapped ends of the hoseband C and I havealso shown the lower part of the body E as provided with flanges cadapted to extend at each side ofthe hose band C to guard against alldanger of the body E turning as the nut K is turned to tighten the bandC, although these side flanges c are not essential.

From the foregoing description it will be seen that when a hose band Chas been placed upon the hose A in the position indicated by Figs. l and2 of the drawing, the pin g will be passed through the hole f in thetongue Z of the band, and, by turning the nut K the head G of the screwH will be moved upward, drawing with it the tongue CZ of the hose bandand firmly tighten the band about the hose. When the band has beensufficiently tightened, the screw K may be turned in reverse directionand the tightener may be then removed from the band. f

I-Iaving thus described my invention, whatI I claim as new and desire tosecure by Letters Patent, is l l. A hose band tightener comprising abody portion having a broad, concavedt'ace at its" inner end and saidbody portion having correspondingly curved flanges at the side edges ofsaid face for engaging the side edges of the band, alongitudinallymovable screw mounted in a guide-way in said body portionand held against rotation therein, said screw having a laterallyprojecting pin at its lower end for engaging the end of the band and ahand nut on said screw engaging the outer end of said body portion,substantially as described.

2. A hose band tightener comprising a body portion having a broad,cylindrically concaved face at its inner end adapted to rest upon theoverlapping ends of the band and having correspondingly curved flangesat the side edges of said face for engaging the .movable screw providedWith a head'eorref spending 1n cross-section to said chamber andnon-rotatably guided therein, a pin `for en-g gaging the end of the bandXed to said head and laterally projecting through the open side of saidchamber, and a hand nutl on said-'screw engaging the'outer end of saidbody portion*substantially as described.

v'3. A hose band ftightener `Comprising a body portion having a Jbroad,oylindrioally eonoaved, inner'end adapted to-res't upon the overlappingends of lthe "band and :having abhamber therein of 'angular orossseotionwith an open slot at one side, said slot beingolosed at the upper end ofsaid body portion, Aa longitudinally vmovable screw provided at -itslower end with a head corresponding in cross-section to the chamber ofsaid body portion and non-rotatably guided therein, a pin for engagingthe end of the band fixed vto said head and laterally pro- HENRY GIBBS.
